Disabling Concurrent Logon Sessions on EG

turcay — Thu, 06 Aug 2015 13:19:06 GMT

The link below has the instruction for disabling Concurrent Logon Sessions for Web Applications. Is it possible to do the same for EG? If so, is there any link or document related to it?

I have customized the startup script that is called by the spawner when a workspace session is launched.

(/...../WorkspaceServer_usermods.sh)

It checks for similar processes run by the same user, and if a certain number of lines is exceeded, terminates without starting SAS.

See here:

LIMIT=4

COUNT=`ps -ef|grep bridge|grep spawned|grep $USER|wc -l`

if [[ $COUNT -gt $LIMIT ]]

then

#document the fact in the user's home directory in a log file

date >> $HOME/.limit.log

exit 1

When you can get your hands on the EGUIDE profile.... 51225 - How to set the number of parallel processes that SAS® Enterprise Guide® can execute

Would advice Kurts approach . As I see Chris is a liking that one also I am getting hope this kind of approaches are getting accepted by SAS (often being blocked).

Hi Kurt, Can we change your Unix script for Windows OS env., or how to run on Windows Server this script (in order to prevent same user same time in diferent hosts)

The script as written won't work on Windows. The command "ps -ef" is a Unix only command. The equivalent command in Windows is tasklist. This command will get a list of currently executing SAS sessions:

tasklist /FI "IMAGENAME eq SAS.EXE" /V

The list contains user names which could be filtered further. I'll leave it up to you to investigate further. I'm sure you have IT experts in your organisation that could script a solution. If it involves different hosts then that is going to be tricky...

I am not weighing in on this much, just that Windows can run a lot of unix scripts. It has a unix subsystem (Windows Subsystem for Linux (WSL)). That said, PowerShell should be able to handle this w/o any issues. Process lists are pretty standard in the .NET world. I use them a lot. A quick search showed Get-Process. Either a script or PowerShell should work with similar logic.
